This reproduces the problem
> loadNamespace('graph')
<environment: namespace:graph>
> loadNamespace('bnlearn')
Error: .onLoad failed in loadNamespace() for 'bnlearn', details:
call: setMethod("nodes", cl, function(object) .nodes(object))
error: no existing definition for function 'nodes'
and it's because of the way bnlearn loads itself
if ("graph" %!in% loadedNamespaces()) {
setGeneric("nodes", function(object, ...) standardGeneric("nodes"))
setGeneric("nodes<-", function(object, value) standardGeneric("nodes<-"))
setGeneric("degree", function(object, Nodes, ...) standardGeneric("degree"))
}#THEN
# add the methods.
for (cl in bnlearn.classes) {
setMethod("nodes", cl, function(object) .nodes(object))
setMethod("nodes<-", cl, function(object, value) .relabel(object, value))
setMethod("degree", cl, function(object, Nodes) .degree(object, Nodes))
}#FOR
graph is loaded but not attached, so the generic that it defines is not visible
to bnlearn.
I'm ccing the bnlearn maintainer

Subject: Re: [Bioc-devel] R CMD check problems
I am evidently not expert in this topic. However I was able to get past
the warning/halt you identified by moving the importFrom(bnlearn,...)
statements to the top of the NAMESPACE. I cannot see in the WRE manual how
the order of namespace imports/exports should be controlled. Other minds
will be needed to set this straight.
